SPECIFICATION forming part of Letters Patent No. 532,739, dated January 1 895. Application filed November 30, 1894. Serial No. 530,475. (No model.)

To all whom it may concern.-

Be it known that I, CONRAD ADAMI, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Soda-Water-Dispensing Apparatus, of which the following is a full, clear, and exact description, reference being had to'the accompanying drawings, making partof this specification, in which Figure 1 is a transverse vertical section ofa soda-water-dispensing apparatus embody ing my invention, one of the sirup-cans being shown in elevation. Fig. 2 is a vertical section on the line 2, 2, of Fig. 1. Fig. 3 is an enlarged'vertical section through one end of a sirup-can andthe parts of the apparatus adjacent thereto, showingthe valve operating mechanism. Fig. 4 is a vertical section on the line 4., 4, of Fig. 3, a portion of the apparatus being shown in' elevation. Fig. 5 is a detail in perspective. Fig. 6 is a front elevation of the apparatus, showing one of the locking-plates'turned down to release the cans above the same. Fig.7 is a perspective View of the rack which supports the sirup cans- Figs. 8 and 9 are details to be referred to.

' and improve the construction of soda-water-v My invention has for its object to simplify dispensing apparatus and consists in certain novel mechanism, whereby the discharge valves of the sirup-cans may be conveniently operated by means of push buttons or knobs, as hereinafter set forth.

My invention also consists in the combination with the sirup-cans, of a novel device for locking said cans in place within the canchamber; and my invention furthermore consists in a rack of novel construction for supporting the sirup-cans above the bottom of the can-chamber in such manner as to enable them to be slid in and out with less friction than heretofore, and at thesame time afford a free passage 'for'the water or moisture to thebottom of the can-chamber from which it escapes by a suitable drain-pipe connected therewith.

In the said drawings A represents the outercasing of the apparatus, composed, as usual, of marble or other suitable material, and B the metal lining of the same.

I C is the ice-box, beneath which is the canchamber D for containing the long narrow sirup-cans G, which are arranged side by side and adapted to be slid horizontally in and out of the chamber D through the front of the casing, which is left open at a for this purpose. Each can is provided on its upper side with the usual opening through which it may be filled, said opening being provided with a cover a. I

To the casing in front of the can-chamber issecured'a'serie's of narrow metallic strips 20 as shown in Figs. 4, 6, and 8, which form partitions between the front'ends of the sirupcans, said strips 20 being secured at their lower ends to a horizontal plate 21 extending beneath the cans as shown in Figs. 3, 4, and 6 and provided with slots 22 for the reception of nipples to be hereinafter described, projecting from the bottoms of the cans, said slots being left open in front to permit of the ingress and egress of the nipples as the cans are slid in and out of the can-chamber.

The flooror bottom b of the can-chamber D is inclined downward toward the rear as shown in Fig. 1, whereby the water produced by condensation is caused to flow to the inner end of the chamber, from which it escapes sage of a can between each pair of plates,

which thus form guides for the cans to slide on, the upper vertical members 9 of said plates forming low partitions between the cans, while the flanges or horizontal members h of said plates form narrow ledges upon which the cans maybe easily slid in and out ofthe can-chamber with very little friction, thus facilitating the operation of removing and replacing the cans and reducing the wear upon the bearing surfaces. Furthermore the open spaces between the plates and rods of which the rack is composed permit the water produced by condensation within the canehamber to pass freely to the bottom of the same from which it escapes by the pipe (I, as previously explained. The lower vertical members g of the plates I which rest on the bottom of the can-chamber are made tapering or inclined along the lower edge in order that the cans may be supported with their bottoms slightly inclined downward toward the front to insure complete drainage. The above described removable rack can be cheaply and easily made and is much simpler and less expensive than the ordinary supporting and guiding devices heretofore employed for horizontally sliding sirup-cans of this description.

Each can G is provided at its front end on the under side with a projecting nipple 10 into which is screwed from the outside a removable valve-seat i forming the outlet through which the sirup is discharged into the glass, which is placed within the usual recess J at the bottom of the apparatus.

7a is a valve which is fitted to the valve-seat z' and is provided with a vertical rod or spindle Z extending up within the front portion of the can G, and passing through a flat-screwcap or fitted to an opening it in the top of the can through which the valve and valve-rod may be removed when required. Between the under side of the cap on and a collar 13 on the valve-spindle Z, is a spiral spring g which serves to keep the valve upon its seat. To the top of the valve spindle Z is secured by means of a nut t, a cap-plate to having an inclined under surface against which fits the upper inclined side of a wedge-shaped slide L, to the front of which is secured a pushknob or button M, the horizontal stem 12 of which passes through the front of a box or casing w removably secured to the top of the can and inclosing the cap-plate it, slide L, and parts connected therewith. The slide L is provided with a central vertical slot j through which passes the valve-spindle Z, said slide when pushed in by means of the button M acting upon the cap-plate u and raising the valvespindle Z and valve it against the resistance of the spring q to permit the sirup to flow into the glass beneath, the parts being returned to their original positions by said spring when the pressure of the finger is removed from the button M. Projecting rearwardly from the slide L is a horizontal red I) which engages a forked guide 0 which in connection with the stem 12, red Z and slot j serves to keep the slide L in its proper position as it is operated by the push-button. A spring d is preferably placed between the guide c' and the rear end of the slide L to assist the spring q to close the valve is; but this spring d may be dispensed with if desired.

In the upper and lower surfaces of the slide L are formed longitudinal grooves e within which are placed anti-friction balls f which bear respectively upon the inclined cap-plate U and the flat upper surface of the screw-cap m, the slide L being thus provided with ball bearings whereby it is caused to move with a minimum of friction, the operation of the valve being thereby greatly facilitated.

By making the valve-scat t' removable from the outside of the can, as above described, it can be easily taken out when obstructed or when cleansing or repairs are required. A slight annular depression 18 is formed around the valve-seat 2', to receive the last drops of sirup in the can, thereby insuring the complete emptying of the same.

I will now describe the device by means of which the cans are locked in place after having been pushed into the can-chamber. N, N, are narrow plates which are hinged or pivoted to the front of the casing at 16, each plate being of a suifieient length to extend beneath the front end of a series or group of cans as shown in Fig. 6. Each of these plates is provided with a series of apertures 9 into which fit the nipples 10 of the sirup-cans when the plate is swung upward into a hori zontal position as shown in Figs. 3 and 4, thus preventing the cans from being withdrawn until the plate is swung down into the position shown at the right hand side of Fig. 6. When swung upward into a horizontal position these plates are supported by laterally swinging brackets P, P, mounted in bearings h, the central bracket P having two branches 25, 30 whereby itis adapted to support the ends of the two adjacent plates N as shown in Fig. 9, it being merely necessary to swing the bracket 1 to the right or left according to the locking plate which it is desired to release.
